Bats are natural reservoirs of several important emerging viruses, and because cross-species transmission appears to be quite common among bats, it's important to study bats in a community context rather than concentrating ...

Machine learning can pinpoint rodent species that harbor diseases andgeographic hotspots vulnerable to new parasites and pathogens. So reportsa new study in the Proceedings of the National Academy of Sciences led by Barbara ...

By studying fossilized teeth from thousands of extinct rodent species, UC San Francisco and University of Helsinki scientists have shown how fundamental evolutionary mechanisms drive the emergence of novel mammalian stem ...

A group of researchers from the University of Helsinki and the Universitat Autònoma de Barcelona have been able experimentally to reproduce in mice morphological changes which have taken millions of years to occur. Through ...

The subfamily of rodents known as Murinae (mice, rats, etc.), which first appeared in Asia 12 million years ago, spread across the entire Old World (Eurasia, Africa, Australia) in less than 2 million years, a remarkably fast ...

Two species of tawny brown singing mice that live deep in the mountain cloud forests of Costa Rica and Panama set their boundaries by emitting high-pitched trills, researchers at The University of Texas at Austin have discovered.

Social monogamy, where one breeding female and one breeding male are closely associated with each other over several breeding seasons, appears to have evolved as a mating strategy, new research reveals. It was previously ...

For territorial animals, such as beavers, "owning" a territory ensures access to food, mates and nest sites. Defending that territory can involve fights which cause injury or death. How does an animal decide whether to take ...
